Installation

Install from the GitHub repository using devtools (with R version 4.3.0 or higher):

if (!require("devtools", quietly = TRUE))
    install.packages("devtools")
devtools::install_github("BIMSBbioinfo/VoltRon")

Depending on the number of required dependencies, installation may be completed under a minute or may take a few minutes.

On Windows and MacOS, OpenCV will be downloaded automatically upon installation. However, Rtools may be required to be downloaded too, hence this may take some time!

On Ubuntu we provide a set of instructions that may help users to build OpenCV with necessary headers here.

On Fedora you may need opencv-devel:

yum install opencv-devel

Docker Hub

You can also run VoltRon from a container already available in Docker Hub. The docker image is based on the Rocker Project and can be run from the terminal like below:

docker run --rm -ti -e PASSWORD=<yourpassword> -p 8787:8787 amanukyan1385/rstudio-voltron:main

Then, start the RStudio session from the browser at http://localhost:8787/ and enter rstudio as username and <yourpassword> as password.

See here for more instructions on how to run the container using Docker Desktop.

Tutorials

Please see the Explore section in the VoltRon website for tutorials, example scripts and analysis found in the preprint. Tutorials include links for accessing necessary data to run scripts across all tutorials.
